Water leakage treatment device of rod mill for recycling casting water glass used sand

Abstract

The invention discloses a water leakage treatment device for a rod mill for recycling casting water glass used sand. The water leakage treatment device comprises a cylinder, a bolt port is formed in the inner wall of the cylinder, a lining plate bolt is arranged on a lining plate, the lining plate is fixed on the inner wall of the cylinder through the lining plate bolt, the adjacent edges of the lining plate are attached to each other, and a waterproof rubber mat is arranged at the side, attached to the inner wall of the cylinder, of the lining plate; a fixed sleeve is further arranged on the end face of the side, close to the waterproof rubber mat, of the lining plate and is hollow, the waterproof rubber mat is arranged in the hollow interior of the fixed sleeve, the outer wall of the waterproof rubber mat is attached to the inner wall of the fixed sleeve, and a plant fiber layer is arranged on the end face of the side, away from the lining plate, of the waterproof rubber mat and is hollow; and a bolt shank is sleeved with the hollow part of the plant fiber layer, and the end surface, away from the lining plate, of the plant fiber layer is attached to the inner wall of the cylinder. According to the water leakage treatment device, a sleeve and the plant fiber layer are arranged at the outer side of the waterproof rubber mat, so that the problems that the cylinder frequently leaks water and the bolt is easy to loosen are solved, the equipment operation rate is greatly improved, and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to a grinding device, in particular to a water leakage treatment device of a rod mill used for recycling cast water glass old sand. Background technique [0002] China is the largest casting production country in the world today. There are more than 20,000 foundry sites, and the annual consumption of sodium silicate quartz sand exceeds 30 million tons. The discharge of a large amount of casting sand not only pollutes the environment (sodium silicate sand contains alkali) but also Waste of resources, so high-quality, low-cost recycling technology using water glass casting waste sand is urgently needed. [0003] The existing rod mill is used to solve the problems of separation, shelling and impurity removal of flying dust and large plate sand in the process of casting waste and regeneration. The multiple round steel rods in the inner container are used to roll and grind the 2-5cm large-grain hardened sand after the primary crushing...

AI Technical Summary

Problems solved by technology

In the technological process, the built-in round steel rods repeatedly perform frequent work on the reinforced liner during the process of gravity rolling and rotating collision, resulting in loosening of the bolts fastening the liner, plus the residual temperature of the casting sand (200-400°C) and The heat energy generated by the work of the rod mill is directly transmitted to the waterproof rubber pad through the cylinder, so that it will expand and soften when heated, and then leak water.

[0004] The above-mentioned existing solutions have the following problems: the production or maintenance personnel do not regularly strengthen the liner bolts on the rod mill and replace the waterproof rubber pads. Water leaks after being deformed by heat and pressure. If maintenance personnel neglect inspections or fail to replace them in time, in serious cases, the screw will break or the nut will fall off and fall into the inner tank. When replacing, you must manually enter the inner tank for replacement, and the process is very frequent. , and there are potential safety hazards, and the maintenance cost is also high
